Explore the concept of smart cities and their sustainability through open source projects in this 30-minute conference talk by Yoshitake Kobayashi from Toshiba Corporation. Delve into the challenges faced by long-lasting infrastructure systems such as power plants, radar systems, traffic lights, and weather systems. Discover how the Civil Infrastructure Platform (CIP) aims to address issues of resource drain, fragmentation, and duplication of effort in building these systems from scratch. Learn about CIP's goals to accelerate the implementation of Linux-based civil infrastructure systems, leverage existing open source foundations, establish de facto standards through base layer reference implementations, and influence upstream projects to meet industrial needs.
